have a 355 sportmod,500holley,automatic. run a 3/8 high banked track car runs great down the straights until you get to corner then then it starts stumbuling(like a missing stumble) then off the corner it will run fine.it was a used car when i got it thinking it has to be a fuel issue ive replaced the fuel line,checked the pickup tube it the fuel sell,changed the power valve because it did backfire when it started once, lowered the float level and adj carb settings and nothing seems to help. anyone have any troubles like this or have any ideas on what to look at. thanks
